I can feel like if I was in the mountain just by looking at this photo. This a great shot !
The composition is perfect with the elk on the left size and the rock on lower right corner. The depth of field on and only on the elk, the unfocused rock and the background add a good balance to the image.
The light is not so good but at 1pm you had no choice. The colors aren't very vibrant but it looks natural. If I had the luck to meet such an animal while hiking in the mountain, I won't be difficult with the light !
